Which type of environmental scientist is most likely to study the effects of air pollution on asthma?
the answer is an environmental physician .
Which activity produces the smallest amount of greenhouse gases?
Riding a bicycle produces the smallest amount of greenhouse gases.
Is the concentration of atmospheric carbon dioxide is currently decreasing due to human activities?
Answer. This is false because the rate at which carbon dioxide is being added to the atmosphere is faster than it can be removed.
What is the ultimate source of heat in global warming?
The ultimate source of heat in the process of global warming is carbon dioxide (CO2). It is a green house gas that absorbs energy from sun, which would otherwise be lost to the space. Some of this energy is re-emitted back to Earth, causing rise in the temperature of earth. This results in the global warming.
Is the greenhouse effect caused solely by human activity?
The one that causes the most warming overall is water vapour – though human activity affects its level in the atmosphere indirectly rather than directly. The greenhouse gases that humans do emit directly in significant quantities are: Carbon dioxide (CO2).
What are the impacts of global warming?
Global warming stresses ecosystems through temperature rises, water shortages, increased fire threats, drought, weed and pest invasions, intense storm damage and salt invasion, just to name a few.
Why is it important to stop climate change?
“Climate change exerts a de-stabilizing influence on an already-unstable world,” says Peter deMenocal, a climate scientist with Columbia University. “It adds a fundamental insecurity to people’s lives and livelihoods, from small island nations to the most developed nations in the world.
What is the purpose of climate change?
– Reducing greenhouse gas emissions, such as phasing out fossil fuels, replacing with more efficient and renewable low carbon energy sources, and changing the way we produce food and manage land.
What are the impacts of climate change on human health?
Climate change increases the risk of illness through increasing temperature, more frequent heavy rains and runoff, and the effects of storms. Health impacts may include gastrointestinal illness like diarrhea, effects on the body’s nervous and respiratory systems, or liver and kidney damage.
What are the causes and effects of climate change?
Humans are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
How does climate change affect ecosystems?
Climate change can alter where species live, how they interact, and the timing of biological events, which could fundamentally transform current ecosystems and food webs. Climate change can overwhelm the capacity of ecosystems to mitigate extreme events and disturbance, such as wildfires, floods, and drought.
Can ecosystems survive climate change?
Consequently, it is likely that many ecosystems will not be able to adapt to the additional stress of climate change without losing some of the species they contain or the services they provide, such as supplying sufficient clean water to drink, food to eat, suitable soils in which to grow crops, and wood to use as …
How do we affect the ecosystem?
Impacts from human activity on land and in the water can influence ecosystems profoundly. Climate change, ocean acidification, permafrost melting, habitat loss, eutrophication, stormwater runoff, air pollution, contaminants, and invasive species are among many problems facing ecosystems.
How does climate change affect the economy?
Climate change is now considered one of the greatest threats to economic stability. As well as its serious impact on the environment and people, climate change is one of the biggest threats to economic stability. Heatwaves make us less able to work and reduce productivity.
What are some positive impacts humans have on the environment?
Humans and the environment Cutting down trees and littering have a negative effect on animals and plants. Protecting endangered species and cleaning lakes and seas has a positive effect on the environment. At home you can help the planet by recycling waste and growing plants or vegetables.
Why is it important for us to protect the ecosystem?
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilisation and sustain our economies.
How does human disturbance affect the ecosystem?
Waterbodies suffering from excessive levels of human disturbance are likely to have reduced quality habitat for fish, wildlife, and macroinvertebrates; suffer from water quality problems such as excess sediments and nutrients, litter, and chemical contamination; and are more likely to be unsuitable for recreational …
