Environmental Issues
Our planet has a natural environment, known as ‘ecosystem’, which includes all humans, animals, plants, land and water. Human activities have caused much depletion and destruction of this ecosystem.
Environmentalism advocates the preservation, restoration and/or improvement of this natural environment by controlling pollution and protecting plant and animal diversity. Environmentalists attempt to balance relations between humans and the various natural systems on which they depend to achieve sustainability.
Earth advocates work to protect natural resources and ecosystems through education, activism and the political process. They seek to give the natural world a stronger voice in human affairs.
The environmental issues of today know no borders. We can't just put up fences around natural places to keep humans out. We must protect the entire planet for the survival of all species — plants, animals and people. Governments, businesses, communities and individuals must make better decisions to live in balance with nature. Through science, responsible planning, legislation and daily choices, we can ensure the survival of the ecosystem.
There are many ways you can help to save wild places and wild animals. Volunteer. Recycle. Install solar panels on your roof. Organize an event where you live. Change a habit. Help launch a community garden. Communicate your priorities to your elected representatives. The possibilities are endless! Do something nice for the earth, have fun, meet new people, and make a difference.
ENVIRONMENTAL ISSUES
LAND
The world population is expected to reach 9 billion by 2050. As our population increases, there is even more pressure on forests, grasslands, deserts and other natural areas to provide food, housing and energy for humans. These demands increase the stress of already fragmented natural areas suffering from pollution, deforestation, disrupted migratory routes and changing environmental conditions.
Already, large numbers of people have been declared food-insecure; resulting in a land rush with nations hurrying to secure properties for agriculture and fuel crops. Forests are being cleared at alarming rates, an estimated 18 million acres each year. At the same time, poor agriculture practices lead to millions of acres of land lost annually through soil erosion and land degradation.
Trillions of tons of garbage is produced every year, while more and more goods are produced...resulting in the creation of more waste. Most garbage is buried underground in landfill sites, causing environmental and health concerns.
If we don’t make changes now, future generations will not experience the same plentiful, diverse planet that we know today.
AIR
Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.
Air pollution is caused by polluters who refuse to clean up toxic air emissions, despite proven pollution control technologies. Most air toxics originate from human-made sources, including automobiles, factories, refineries and power plants. Indoor sources include building materials and cleaning solvents.
As the environment suffers, humans suffer from asthma, lung disease, heart ailments, cancer and shortened lives. Acid rain, often caused by pollutants in the atmosphere from automobile or industrial processes, falls from the sky in the form of rain, snow, fog or dry material. Devastating effects to forests, aquatic systems, buildings and human health can result. Air toxics then contaminate our food products, drinking water and soil.
WATER
Pollution, habitat fragmentation and destruction, and overfishing are having devastating effects on our oceans, rivers and lakes. Acidification, caused by increased carbon emissions, degrade coral reefs and corrode the shells of sea creatures. Freshwater ecosystems provide us with drinking water, food, energy and recreation. These ecosystems are also critical to plants and animals. Increased demands for food, energy and material goods have placed unprecedented pressure on these fragile environments. Within the next 20 years, half of the world’s population may face water shortages.
Oceans are a critical part of the earths support system. Acid rain pollutes our seas. Oceans are degraded by spills and chemical runoffs. The largest living structures on earth, coral reefs, are among the greatest storehouses of biodiversity on the planet. Up to 70 percent of coral reefs are expected to be lost by 2050 due to human activities.
Water is under threat from fertilizers and chemical runoff, dumped chemical and industrial wastes, untreated sewage and medicinal residues.
GENETIC ENGINEERING
Genetic modification of plants and animals is a controversial subject, with many experts believing the ill impacts far outweigh the benefits to mankind. Manipulating plant DNA to produce super crops is a dangerous global experiment. When released into the environment, they cannot be recalled.
Genetically modified organisms (GMOs) can spread through nature and interbreed with natural organisms. They can contaminate natural environments in an unforeseeable and uncontrollable way. This is referred to as 'genetic pollution', a major threat to the environment.
Due to commercial interests, the public has been denied the facts about GMO ingredients in the food chain. The absence of labeling laws in many countries denies individuals the power to avoid them.
Biological diversity must be protected and respected. It is fundamental to our planet's survival.
