What is a global evironment problem that needs to be addressed?

Question

I am writing a paper and I need something to write on besides global warming any suggestions!! Also, does it have an engineering solution.

Answer 1

Overpopulation. If we had 20% fewer people, we would have 20% less global warming.

Answer 2

try deforrestation

TREES NOT ONLY PRODUCE OXIGEN or ABSORB CARBON
the world bank pays large subsidies for farmers to plant trees especially a tree called Pawlomia because it is one of the better ones that capture carbon.

plants take in carbon dioxide period they dont take in oxigen at night.

they require carbon dioxide and release oxigen.

in the autemn there is an excess of carbon released because of the dead organic material ,the seas and waters when cool absorb this,in the spring when the new growth requires carbo the warmer waters release it ,so in con junction with the seas and rivers the bio mass on this planet maintains a balanced atmosphere for us to breathe.
now with the mass deforrestation(decrease in bio mass)coupled to the increase in carbon emissions,industrial chimneys,aerosol cans,motor cars,burning of plastics and tires to name but a few ,the carbon production by far exeeds what the bio-mass and the waters can handle,and so effect into global warming and the destruction of the ozone layers,
so to counter act these fatal processes we must reforrest and at the same time reduce our carbon emissions.
most governments are aware of these and many first world countries now include programs to reduce their carbon emissions.

the forrests make most of the water that we can drink or use for plant growth(sweet water)
some is condensed from the sea but that reaches only the coastel aereas .
the bulk ,comes from the forests ,and the rivers come from the rainfall which comes from the trees ,
and the trees with precipitation,feed the rivers when it is not raining and keep them running all year round.

If we kill all the trees,we kill the rivers .we kill the rain. we kill us.
the trees also absorb the heat in the day and heat up the place in the night ,so they keep the temperature confertable to live in.

DESERTIFICATION
desertification is also a result of bad agricultural methods and deforrestation
in the dessert the nights are freezing cold and during the days you burn up

the saharaa is growing by 7 kilometres every day.
two major desserts in northern china are growing together making one giant dessert and,causing dust storms so making thousands of people refugeese

the trees evaporate a mist which ,which protects us from the strong rays of the sun .

in the days of the dinasaurs this planet was under an aquiferus manta ,a mist that covered the entire earth ,and there were no desserts .

Count how many there are today,and all of them are as a result of mans actions.
the sahara used to be forrests
arabia ,irak ,iran used to be fertile lands in biblical times
Ghengas Kahn burned all the forrests here and filled the well with water and so turning vast lands into dessert.

Modern agriculture today is doing the same as ghengas kahn but in much bigger territories.

these are some of the reasons why trees are important.

so plant a tree every week,and help us save the world

read a planet under stress ,plan B --by Lester E Brown.
it is in an Adobe print out as well on the net.

Answer 3

Let us see if we can save some people. I have calibrated gas detectors ,there only 2 gases to be concerned with . Lighter than air which most will explode. Heavier which will smother u. The bad CO gas is heavier and that is how it kills. The Fire DP. has pushed CO detectors and that is good,but I have Sean nobody mention that the CO sensor will only last about 3 years. In the professional world if u are to be exposed ,u always want a calibrated instrument. CO is a very bad gas if it happens in your house and u are up on the bed there is a good chance u will survive. Good luck

Answer 4

Cars-buses-trucks leaking oil.

ENG solution is, repair seals etc. or, invent a better oil seal!

Serious and nasty pollutants

Answer 5

there should be concensus as to whether the planet is cooling or warming up
