HELP NATURE TO HELP US

March 1, 2017 @ 8:08 AM

We can all take notice of our environment. We can learn how our planet works. We can learn how to live on it without making a mess of it. We can help to keep it magnificent for ourselves, our children and grandchildren, and other living things besides us.

You can help by growing your own vegetables and fruits. You can help by planting a tree. Your new plants and trees will help to remove the greenhouse gas CO2 from the air. If you grow some of your own food, you will also help to prevent more CO2 from entering the air from the fossil-fuel-burning trucks, planes, and ships that transport your food to you from far away.

How can I reduce my "carbon footprint"?

Your carbon footprint is the amount of carbon dioxide released into ......

CORAL REEFS IN CRISIS

February 24, 2017 @ 8:08 AM

Coral reef ecosystems are complex, dynamic, and sensitive systems. Although they are geologically robust and have persisted through major climactic shifts, they are however, sensitive to small environmental perturbations over the short-term.

Natural And Human Influences

Slight changes in one component of the ecosystem affect the health of other components. Changes may be attributed to a number of causes but generally fall into two categories, natural disturbances and anthropogenic disturbances. Distinguishing between natural and anthropogenic disturbance is not always simple because the impacts of human actions may not be seen until well after the action has occurred, or may not be seen until it is coupled with a natural disturbance. ......

MOUNTAIN SHAPES AND WHY THEY MATTER

February 22, 2017 @ 9:36 AM

People commonly perceive mountains as pyramid-shaped masses that steadily narrow as they slope upward. But researchers have found they actually have four principal shapes. Not only are pyramid-shaped mountains in the minority, but most ranges increase in area at higher elevations. Besides reshaping the mountains in our mind's eye, these findings could lead scientists to reconsider conservation strategies for mountain species.

The four principal shapes of mountain ranges include: diamond, pyramid, inverted pyramid and hourglass. For all the range shapes except pyramid, land availability can be greater at higher elevations than it is farther down the mountainside. Yet, people's idea that land area steadily shrinks as a ......

GOING GREEN BY EATING GREEN

February 19, 2017 @ 8:39 AM

While there are many lifestyle changes you can make to help the environment, no other lifestyle decision can compare with the positive environmental impacts of veganism.

Veganism is a compassionate lifestyle of daily decisions that reject the exploitation and harm of animals. Vegans do not consume food that is derived from animal sources, do not purchase products made from animal sources, do not use services in which animals are harmed, and do not involve themselves in activities that cause intentional harm or exploitation of living beings. Vegans attempt, as much as possible, to live their lives free from all forms of animal exploitation. It is a humane, responsible and healthy choice.

And not only does veganism help ......

PALM OIL THREAT AND THE ORANGUTAN FIGHT FOR SURVIVAL

February 16, 2017 @ 9:02 AM

Once found all over South-East Asia and even the far reaches of Southern China, orangutans have found themselves squeezed to just the two islands of Sumatra and Borneo. The great red-haired apes have been around for almost 400,000 years, but have seen their numbers dwindle alarmingly from over 200,000 a century ago to only 45,000 presently. The habitats of this iconic animal have been pushed to the rain forests in the northern fringes of the Sumatra island of Indonesia and just the south-eastern part of Borneo, the only two places on earth where they inhabit naturally.

The most important intake of the orangutan is fruit, which makes up almost 60% of the ape's diet. It consumes over 300 food items that include leaves, ......

MOUNTAINS: THE LAST FRONTIER FOR ENDANGERED SPECIES

February 15, 2017 @ 8:43 AM

The threats faced by wildlife around the world continue to increase. Each year, thousands of animal species are lost to extinction. Mountain areas provide one of the last safe havens for endangered plant and animal species. But even these last safe havens are now under threat by irresponsible human activities.

A large number of mammals have taken up homes in mountainous areas. The most cited reason for this is environmental variation, which is the evolution of different species that live in the valleys and mountains. But studies have revealed that the high level of biodiversity in mountains can also be attributed to the protection mountains offer to endangered species. Animals are taking refuge in mountains because we've ......

TROUBLE FOR LEMURS

February 10, 2017 @ 6:43 AM

Deep in the mountainous rainforests of Madagascar, a furry brown and white creature leaps from tree to tree. As it moves high above your head, you notice that two smaller creatures cling to it. You are witnessing the travels of a lemur and her babies. This lemur is called the Milne-Edwards Sifaka. You are lucky because this kind of lemur may be harder to find in the future. That’s because climate change is making it difficult for some lemur mothers to care for their offspring.

Lemurs are a kind of primate. Primates are animals like monkeys, apes, and even humans. This specific kind of primate lives in only one place—the island of Madagascar. Many lemurs, including the Milne-Edwards Sifaka, live in the lush rainforests that are ......

ANIMAL AGRICULTURE IS DESTROYING TROPICAL FORESTS

February 7, 2017 @ 10:07 AM

Deforestation causes drastic loss of tropical forest biodiversity, and most deforestation occurs due to animal agriculture. Remaining areas of undisturbed and recovering forest provide the last refuge for many species unable to withstand the impact of human activity.

As one of the most comprehensive surveys of the impacts of disturbance on tropical forest biodiversity ever conducted, an international team of scientists found where forests had been cleared for animal agriculture, plant and animal life was impoverished and remaining species invariably consisted of the same subset of the original flora and fauna. There is irrefutable evidence that biodiversity is declining across the tropics due to animal agriculture.

The rapid ......

WHAT IS AN ENDANGERED SPECIES?

February 4, 2017 @ 7:04 AM

Life on Earth over the millennia has been defined by the evolution, survival and demise of multitudes of species. The churning of species is part of the life process and extinction is one inevitable component. But humans are now playing a large part in the extinction of many species.

Human activities are responsible for the significant changes in the world's environment. Human activities cause climate changes from industrial emissions and animal argiculture, destruction of wildlife habitat, reduced wildlife populations through hunting and poaching, and ecosystem disruption through pollution and litter.  All these activities are major contributors to a serious decline in wildlife numbers.

HOW OIL HARMS ANIMALS AND PLANTS

February 1, 2017 @ 12:24 PM

In general, oil spills can affect animals and plants in two ways: from the oil itself and from the response or cleanup operations. Understanding both types of impacts can help spill responders minimize overall impacts to ecological communities and help them to recover much more quickly.

Spilled oil can harm living things because its chemical constituents are poisonous. This can affect organisms both from internal exposure to oil through ingestion or inhalation and from external exposure through skin and eye irritation. Oil can also smother some small species of fish or invertebrates and coat feathers and fur, reducing birds' and mammals' ability to maintain their body temperatures.
