Save Our Animals

he earth is comprised of many different life forms, including plants, animals, humans, and other organisms. These various life forms are highly interdependent and have formed important systems that continually reshape the planet's landscapes, oceans, and atmospheres.

Booming human population growth over the last two centuries has put, and continues to put, many of these life-sustaining systems out of balance and in serious jeopardy, endangering many of the plant and animal species that human beings directly and indirectly depend upon for long-term survival.

Bigger human populations naturally mean increases in human activities worldwide, leading to changes in landscapes, oceans, atmospheres, and the path of human history. For example, as noted in the benchmark of this lesson, human activities like reducing the amount of forest cover, increasing the amount and variety of chemicals released into the atmosphere, and intensive farming, have changed the earth's land, oceans, and atmosphere. Some of these changes have decreased the capacity of the environment to support some life forms.

Human populations and activities will continue to grow and to threaten the earth's habitat and capacity to sustain life, putting once flourishing plant and animal species on the ever-increasing endangered species list. The National Wildlife Federation (NWF) forecasts that the human population is slated to reach 8.5 billion in 2025, up from 5.2 billion in 1990. Right now, the NWF asserts that plant and animal species are disappearing at least 1,000 times faster than any other time in the last 65 million years. It also claims that habitat loss is accounting for almost 75 percent of the extinctions occurring now. While statistics become more and more staggering, human beings seem to be doing very little to address these long-term, disastrous issues.
