Twenty-first century threats to our environment—including invasive species, diseases, pollution, and a warming climate—are putting wildlife populations at risk. The National Wildlife Federation unites Americans addressing these environmental threats and protecting our wildlife and their habitats.

Why should threats to plant diversity be taken seriously?

Major Threats to Plant Diversity. It is estimated that there are around 400,000 plant species in the world, and at least 25% are threatened with extinction. Humans are the main cause of extinction and the principle threat to species at risk of extinction. Habitat loss and degradation are the leading threats.

How do humans affect the environment negatively?

Human activity is causing environmental degradation, which is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution.

Why do we celebrate Earth Day?

Earth Day is an annual event celebrated around the world on April 22 to demonstrate support for environmental protection. A month later a separate Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970.

How is biodiversity loss?

Biodiversity loss. Biodiversity loss is the extinction of species (plant or animal) worldwide, and also the local reduction or loss of species in a certain habitat. Reduced biodiversity in particular leads to reduced ecosystem services and eventually poses an immediate danger for food security, also for humankind.

What is meant by environmental crisis?

An ecological crisis occurs when changes to the environment of a species or population destabilizes its continued survival. A few possible causes include: Degradation of an abiotic ecological factor (for example, increase of temperature, less significant rainfalls) Increased pressures from predation.

What are the types of environmental degradation?

Environmental degradation is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. Environmental degradation comes in many types.

What is environmental care?

Environmental protection is the practice of protecting the natural environment by individuals, organizations and governments. Its objectives are to conserve natural resources and the existing natural environment and, where possible, to repair damage and reverse trends.

What causes environmental changes?

What does overexploitation mean?

Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. The term is also used and defined somewhat differently in fisheries, hydrology and natural resource management. Overexploitation can lead to resource destruction, including extinctions.

How do ecosystems benefit humans?

There, ecosystem services are grouped into four broad categories: provisioning, such as the production of food and water; regulating, such as the control of climate and disease; supporting, such as nutrient cycles and oxygen production; and cultural, such as spiritual and recreational benefits.

How does climate change affect our lives?

As the climate warms, it changes the nature of global rainfall, evaporation, snow, stream flow and other factors that affect water supply and quality. Specific impacts include: Warmer water temperatures affect water quality and accelerate water pollution.
