The impact of flippant environmental decisions has realized more harm than was imagined for the environment, and this has, as a result, encouraged more research into the science of environment, which is hoped to make the earth more habitable for the present and future generations.

On, the bulk of the research to be done is in choosing energy network, to realize which of the many available actually poses more benefit than harm to the environment.

Below are the top environmental research topics that should be considered by college students:

The Effect of Global Warming:

Global warming is only an aspect of climate change, but there is so much to be spoken on it, because it is furthered mainly by human activities like farming, deforestation, and the burning of fossil fuels. Topics on this subject may include issues on the impact of enhanced greenhouse effect, the consequence of the atmospheric carbon dioxide emitted as a result of the use of fossil fuel, ways alternative energy may prove useful to balance the planet’s rising temperature.

Biodiversity, and the Ecosystem:

Biodiversity concerns the living things on earth. This includes plants, animals, micro-organisms, amongst others. While before often overlooked, more attention is now being paid to this area of environmental science, because it has been realized that bio-diversity improves productivity of the ecosystem.

The Ozone Depletion:

The ozone depletion has posed a lot of problems to the environment, and this, because it increases the level of Ultraviolet radiation on the earth’s surface. The problem does not stop with the environment however, affecting humans and other organisms alike. Research topics on this subject may concern the threat it poses to the ecosystem, the impact of greenhouse gases, and eutrophication.

Renewable Energy:

Alternative means of energy are getting developed to combat rising environmental problems; from wind energy, to solar, and to hydro energy. Analysis may be done on the operation of the performance of the solar system and what models serve best to provide clean energy; to the effect of data in the advancement of photovoltaic (PV) to reduce the cost of solar energy.


A treatment whereby natural organisms are used to break down harmful materials so they become less toxic or all together losing its toxicity, bioremediation is a topic that is enjoying a lot of exploration in environmental science because the less toxic emissions on the environment, the less danger is posed to environmental health.


The major forms of pollution that may be explored in an environmental research topic may include air pollution, water pollution, plastic pollution, and radioactive pollution. The hazards posed to the environment from metals deposited on the soil can be explored, as well as the long term impact of emissions.

Environmental Justice:

More climes deal with certain environmental problems than others, such that it sometimes translates to the inaccessibility of important things like clean air, green spaces, and good soil. Marginalized populations deal greatly with this, and research may be done on what alternative energies may serve best; the importance of environmental impact assessment; and how to promote sustainable land management.

Conservation biology, limnology, and urban ecology are other subjects that may be explored when choosing an environmental research topic, but the seven above are the top to be explored.
