'action on environmental conservation' Re-write paragraph in suitably academic style

Hi everyone, I am now practicing to paraphrase a paragraph.
Please help me to check my paraphrase in terms of the academic style.

Original paragraph:
If we do nothing about the problem, we will certainly make our land and water worse. In my opinion, we can do at least three things to solve the problem. Firstly, we should minimize the amount of fuel burnt everyday by stopping using cars when it is not necessary, trying to find more kinds of energy and then we can reduce the amount of carbon dioxide in the air. Secondly, we should stop cutting down the trees and grow more trees on the planet. We should save our trees. The reason for doing this is that trees can change carbon dioxide into oxygen so our planet will have more oxygen. The third thing we could do is force people to stop dumping things into the land because that will cause the land and water to be polluted.

My paraphrase:
Without action on environmental conservation, land and water will be degraded. There are three main solutions to deal with the problem. The first solution is reducing petroleum usages everyday in order to decline the amount of carbon dioxide in the air. For example, vehicles should be used when it is necessary only and also petroleum power ought to be attempted to replace with other kinds of energy. The second solution is that deforestation should be banned, and trees should be grown. This is because trees are able to produce clean air by changing carbon dioxide into oxygen. The last solution is that because damaging into the land is a main cause of the land and water pollution, so the policy to preserve the surface of land should be made.

solution is to reduce petroleum usages everyday

This is because trees are able to purify/filter the air

by converting carbon dioxide into oxygen

so the policy to preserve the surface of land should be implemented.

I think the paragraph pertains to environmental pollution; as such, you might want to include "air" along with land and water.

According to your first sentence, if corrective action is not taken then the quality of the land and water will be adversely impacted. Of course, whether action is taken (or not), the quality of the land and water has already been degraded to some extent. This implicit assumption helps form the premise of your putative argument that the damage to land and water will be considerably worse if efforts are not undertaken to conserve the environment.

As it were, you say that without conservation efforts, land and water will be degraded; that is, the argument is posed as a problem solely as it relates to your proposition that "Without action on environmental conservation, land and water will be degraded." In other words, you skipped the chain of facts that would support your putative proposition. Your paragraph presupposes the case and then outlines proposals that tacitly validate it.

One might ask how the author could know and warn about something that will happen -- if, supposedly, this "something" will only happen as a direct result of inaction.

There is no problem to be dealt with, per se, if you're predicting the effect(s) of something that has not materialized. In layman's terms, the three solutions to the problem could be interpreted as solutions designed to forestall the potential aftermath of a situation where people don't make efforts to conserve the environment. Or, the three solutions could be interpreted as suggestions to mitigate our impact on the environment.

On the three ideas for reducing damage to the environment:

- The use of petroleum is a major contributing factor to Greenhouse Gas Emissions; limiting petroleum use will lead to a direct decrease in Greenhouse Gas Emissions. Reducing petrol use can be accomplished by reducing usage voluntarily, by adopting alternative energy sources, and by designing more effective emissions control systems in vehicles.

- Plants and Trees serve a critical function because they absorb Carbon Dioxide and release Oxygen. Carbon Dioxide accounts for 84% of Greenhouse Gas Emissions. Therefore, deforestation should be regulated very tightly with reforestation mandated. Reforestation projects should be expanded and better researched to guide their implementation in mitigating climate change.

- Drilling, Dumping, Oil Spills, Nuclear Energy, and other industrial related incidents have damaged and polluted waterways and land. We must learn to appreciate the beauty and the necessity of nature to our daily living and to the lives of so many others, sooner rather than later.
