What do you believe is the greatest threat to animals and why?

Habitat loss—due to destruction, fragmentation, or degradation of habitat—is the primary threat to the survival of wildlife in the United States. Climate change is quickly becoming the biggest threat to the long-term survival of America’s wildlife.

What will happen if animals disappear from Earth?

Answer: (a) If the plants and animals disappear from the Earth’s surface, then the ecological balance will be disturbed. Without plants there will be no oxygen available for breathing after some time and everybody will die. These animal and plant species, including humans, are all interdependent.

How do human activities affect the environment class 10?

Human activities contribute to climate change by causing changes in Earth’s atmosphere in the form of greenhouse gases, aerosols etc. Burning of fossil fuels such as coal, oil and natural gas to generate large amounts of energy is the human activity that has the greatest impact on global warming.

What effects do humans have on wildlife?

The loss of wetlands, plains, lakes, and other natural environments all destroy or degrade habitat, as do other human activities such as introducing invasive species, polluting, trading in wildlife, and engaging in wars.

Can you live without animals?

Originally Answered: Can humans survive without animals? Unfortunately not, as animals contribute to nature in ways that we will never be able to. For example, without bees, many plants and therefore our food, will not be able to be produced. Without birds, seeds will not be dispersed, and many trees will disappear.

How do activities affect the environment?

Human activities affect the environment by contributing to air pollution, or the emission of harmful substances into the air. These toxins can exert tremendous effects on the natural world, leading to environmental degradation and problems like acid rain and harmful algal blooms in the ocean.

Will climate change make humans extinct?

Extinction risk is increased under all RCP scenarios, with risk increasing with both magnitude and rate of climate change. Many species will be unable to track suitable climates under mid- and high-range rates of climate change during the 21st century. Lower rates of climate change will pose fewer problems.
