Energy efficiency technologies are capable of using the same amount of energy we normally would, but in reality, using less resources. Examples of these types of energies are used to provide power, heat,
and cooling systems.

Researchers are also looking into creating low-carbon technologies in order to bring down the emissions of carbon, which is a cause of global
warming, along with methane and nitrous oxide.

Using less fossil fuels is always a good way to help reduce the risk of global warming. By not adding
any coal-burning (mainly coal mostly consisting of carbon) power plants, there will be less carbon
emitted into the atmosphere.

Reusing sources of energy such as solar power, wind power, and others is also a good way to help
reduce the amount of pollution in the air. Renewable sources of energy is an effective technology to help
prevent this.

As for vehicles and methods of
transportation, by using low-carbon fuels, that can be a good way
to help reduce the emission of carbon into our atmosphere. Also
by relying less on methods of
transportation to go places and using less of this energy, that
could also contribute to help solving the
problem of releasing carbon into the atmosphere.

2) Describe some high-tech solutions that have been suggested to deal with
the effects of climate change.
Large vertical pumps were to be used to transfer cold ocean
water from the deep to the surface. Drawn up by Chris Rapley and James Lovelock, the
scheme is based on the hypothesis that colder water absorbs more
carbon dioxide.[image source]: http://i2.wp.com/davidbrin.files.wordpress.com/2013/06/ocean-pipes-1.jpg?resize=300%2C300
American physicist, Lowell Wood, believes in launching giant mirrors into orbit to block out
sunlight. The mirrors would not completely block it out, but would filter harmful infrared radiation.

Paul Crutzen proposed using sulphur rockets to create clouds to block out the sun. The idea is
based on evidence that volcanic explosions accompanied by massive clouds of sulphur helped
cool the Earth's temperature by 0.6C.

3) What are some simple technologies or low-tech solutions that could
minimize the effect of human activities on the environment?
One of many solutions is by painting roofs white, the sunlight
could better reflect off of them instead of
having it being absorbed, thus sending
away some of the carbon dioxide
emissions out of our atmosphere. Though
we would need several white roofs to actually
have a noticeable effect on this climate change, it is one of many low-tech solutions that we
as humans can do.

Of course, another solution is to plant more trees. Deforestation is a big cause to greenhouse gases being emitted, and by planting more trees and
cutting down less, this could help further solve the problem and help reduce the risk of any negative
climate change.

Another solution is our use of electricity. By using less electricity,
greenhouse gas emission can be
further prevented. By simply unplugging
devices when they are not in use could make a really big difference
in the amount of greenhouse gases being emitted and released into the
atmosphere.

It is evident that climate change is becoming more of an issue than it was before, and that is all the
more reason for more people to be taking action in preventing these negative changes. Even by
changing how we live in the simplest ways possible (ie: unplugging devices when they’re not in use, using low-carbon fuel, etc.), it can make a bigger
difference if more people contribute.

Lower-tech solutions can be easy, though it would be more effective if more
people had a better understand as to what is
going on with Earth’s climate. If we start to make changes in our
lifestyles to help improve our environment and
climate now, we could be setting an example for future generations. We
could be nearing a society in which we have
less environmental issues than we have right
now.
