What has influenced human population growth?

What has influenced human population growth?

Factors that influence human population growth include: Healthcare/access to health care/medical technology/ability to fight or prevent disease. Availability of birth control/availability of family planning education/use of birth control. Political and/or economic stability/government stability/war.

What does an indicator species tell us about the health of an ecosystem quizlet?

the indicator species helps you determine the health the an ecosystem and the carrying capacity tells you how many species an environment can hold so all together the indicator species can dictate how large or small the carrying capacity will be.

What does an indicator species tell us about the health of an ecosystem?

What does an indicator species tell us about the health of an ecosystem? The indicator species helps you determine the health of an ecosystem and the carry capacity tells you how many species an environment can hold, therefore the Indicator species can dictate how large or small the carrying capacity will be.

How does the greenhouse effect keep Earth warm quizlet?

How does the greenhouse effect keep Earth warm? By trapping some of the infrared rays, the atmosphere around us remains warm and stable. This is necessary for sustaining life. This naturally occurring greenhouse gas varies depending on how humid it is.

Which causes an increase in greenhouse gases?

1. Burning of Fossil Fuels: Fossil fuels like coal, oil and natural gas have become an integral part of our life. When these vehicles run, they release carbon dioxide, which is one the main gas responsible for increase in greenhouse effect. …

Does melting ice causes Earth to warm even further?

The sun’s rays enter earth’s atmosphere and are trapped by greenhouse gases and they heat up the earth. Melting ice causes the earth to warm even further. True; the ice would’ve reflected more sunlight away from the earth’s surface, just like a white t-shirt. Why does cutting down trees increase global warming?

Could we survive on earth without the greenhouse effect quizlet?

What is the greenhouse effect? No we would not be able to survive because without these gases, the Earth would be too cold for humans, plants and other creatures to live. The two largest greenhouse gases are Co2 and methane which comes from fossil fuels ,coal ,oil, and other gases.

What would the Earth be like without greenhouse gases?

Greenhouse gases in the air, mainly carbon dioxide, methane and water vapour, trap radiation from the Sun and act like a thermal blanket around the planet. Without the greenhouse effect, the Earth would have an average temperature of -18 °C and be covered in ice. Life as we know it would not be able to survive.

Which two of the following are strong greenhouse gases?

Carbon dioxide (CO2) and methane (CH4) are two powerful greenhouse gases produced by the carbon cycle. In this section, you will learn how the carbon cycle regulates Earth’s climate through the greenhouse effect

What is the consequence of greenhouse gases are not present especially in the Earth atmosphere?

If greenhouse gases were not in the atmosphere, all the infrared light radiated by the Earth would go back out to space, leaving the Earth too cold for life. But the greenhouse gas molecules absorb the infrared light, and then re-radiate some of it back to the Earth’s surface

Why are greenhouse gas emissions bad?

Greenhouse gases have far-ranging environmental and health effects. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases

How hot is Earth without an atmosphere?

Without an atmosphere, our world would be as cold as the lifeless moon, which has an average temperature of minus 243 degrees Fahrenheit (minus 153 degrees Celsius) on its far side. Because of the greenhouse effect, Earth maintains an overall average temperature of around 59 F (15 C)

What would happen if greenhouse gases decrease?

To illustrate the risk of insufficient scientific communication, if all greenhouse gas emissions were to be completely stopped starting this year, the public would expect immediate, rapid declines in global warming. However, temperatures are projected to rise at an accelerated pace for at least 13 more years

Why we should stop global warming?

A warmer climate increases public health challenges like heat aggravated illnesses, increases in vector borne diseases, and decreased access to safe water and food. Cutting short-lived climate pollutants can slow the rate of warming and lower public health risks.

How do we stop global warming?

How You Can Stop Global Warming

  1. Speak up!
  2. Power your home with renewable energy.
  3. Weatherize, weatherize, weatherize.
  4. Invest in energy-efficient appliances.
  5. Reduce water waste.
  6. Actually eat the food you buy—and make less of it meat.
  7. Buy better bulbs.
  8. Pull the plug(s).

What will happen if greenhouse gases continue to increase?

Continued emissions of greenhouse gases will lead to further climate changes. Future changes are expected to include a warmer atmosphere, a warmer and more acidic ocean, higher sea levels, and larger changes in precipitation patterns.

What is the biggest contributor to greenhouse gases?

The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation

Can humans stop global warming?

Yes. While we cannot stop global warming overnight, or even over the next several decades, we can slow the rate and limit the amount of global warming by reducing human emissions of heat-trapping gases and soot (“black carbon”).

What causes global warming?

Q: What causes global warming? A: Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface. That’s what’s known as the greenhouse effect

How serious is global warming?

Higher temperatures are worsening many types of disasters, including storms, heat waves, floods, and droughts. A warmer climate creates an atmosphere that can collect, retain, and drop more water, changing weather patterns in such a way that wet areas become wetter and dry areas drier

How important are accurate climate predictions?

These predictions and results can also suggest how to mitigate the worst effects of climate change, and they help decision-makers to prioritize environmental issues based on scientific evidence
