6 additional persuasive environmental speech topics

Persuasive environmental speech topics to increase the quality of your persuasive communication skills, detailed layouts on Natural Resources, Radio Active Waste Management, and Intensive Farming are even applicable on essay writing goals.

Can We Write Your Speech?

Get your audience blown away with help from a professional speechwriter.
Free proofreading and copy-editing included.

Examine the opportunities I offer, and assemble you own speaking text based on the sample series of reasons below.

That logic reasoning process in the end will result in a nice and substantial blueprint, and a sample argumentation scheme for a debate on good persuasive environmental speech topics.

Excessive Use of Natural Resources Leads to Depletion In The End.

I. Industrial development destroys the environment by left over and residue materials such as: a. High concentrations of metals;

b. Toxic substances and chemically changed minerals;

c. Debris and litter;

d. Radioactive infected ground at industrial sites.

II. Large-scale soil erosion because surface soil washes away due to influencing water tides and winds streams. a. Intensive plowing and draining of farm land.

b. Planting of genetically singular crops in combination with applying too much fertilizers and pesticides.

III. Abnormal huge irrigation systems in farming: a. Salination of the ground, ground water, and creeks and wells.

b. Excessive withdrawal of ground water reserves.

IV. Surface and underground mining for gas, oil and minerals devastate land and oceans and mutilates our world. a. It causes every growing desolate and desert spots.
V. Deforestation – the rainforests in Latin America are the obvious victims – you not need grown-up persuasive communication skills to bring this to reason. a. Including their biodiverisity of forest animals;

b. Exotic plants;

c. And micro-organisms.


Radioactive materials are – without exception I would state – firm persuasive environmental speech topics and essay discourse themes for students. E.g.:

Radio Active Waste Management.

I. There are three critical stages in the radio active waste management flow: a. Spent nuclear fuel that is stored temporarily at power plants, also known as interim storage.

b. The control of the risky transportation of radioactive materials.

c. The final storage and disposal, to protect future generations from potential threats.

II. There are three levels of contamination: a. The low level waste: 1. Nuclear reactor complexes, and also hospitals and research departments of industrial corporations produce low level waste.

2. It is considered as hazardous during at least thirty years and have to be isolated for three to five-hundred years from now.

В b. The intermediate level waste: 1. Heavier toxic materials from nuclear power plants constrained with the obligation to secure it in concrete.

2. Solid and semi-solid organic substances, chemical sediment from metal bonding processes.

В c. The high-level nuclear waste: 1. Exceeding the other acceptable amounts, highly dangerous to humans and other organic species for thousands of years in the future.

2. Residual nuclear waste in nuclear electricity generation complexes in the uranium fuel cycle.

3. Plutonium and uranium fuel in a nuclear reactor.


Intensive farming has many pros and cons. In the next example I deal with the cons. Note that each of them could be used as single persuasive environmental speech topics for a debate or essay:

The Disadvantages of Intensive Farming.

I. Disavantage One: often factory-like farms use an overkill of chemical fertilizers, insecticides, and pesticides. a. Pesticides kill helpful insects. E.g. bees, ladybugs, and mantis.

b. Chemical residues in meat, in fruit and in vegetables end up in our human food chain.

c. The soil and water streams are contaminated.

II. Disavantage Two: The problem of overcrowded livestock feedyards and poultry holding facilities full of pigs, cows, and chickens. a. Their waste causes environmental pollution.

b. Great risk of livestock diseases and infections for humans.

III. Disavantage III: Forests fires to make way for farmland. a. Cause erosion of the soil.

b. Reduce the wild animal population.

IV. Disavantage Four: Hormonal preparations to stimulate growth. a. This must make genetic selection easier and have to facilitate the extensive breeding of animals.


You also could take the opposite side and defend the pro-intensive farming arguments by attacking and replacing them for reasons in favor of the supporters of intensive farming. That will provoke immediate discussion among your listeners. Furthermore I would like to share alternative options for persuasive environmental speech topics:

  • Endangered species;
  • Marine debris and microplastics;
  • The sea level rise.

Endangered species – The international list of protected animals. E.g. the Red List of the International Union for the Conservation of Nature IUCN. Sharpen your persuasive communication skills and judge the conditions for protection.

Marine debris and microplastics – More and more are our ocean, seas, lakes and rivers polluted. Littering: plastic bottles, bags, and so on. Persuade your audience to act. Let them support coastal volunteer operations to remove and prevent debris.

The sea level rise – What is bad about it? What are the predictions of meteorologists regarding the reported weather and climate changes? What should we do to stop it? Is it possible to stop the rise of the sea level anyway?


  1. The fundamentals of logistics for oil and gas exploration.
  2. Wildlife protection programs.
  3. Plants, animals and organisms that live in the ocean.
  4. The greatest rainforests in the world.
  5. Facts and figures of littering in our community
  6. Domestic water waste treatment plans.
  7. Safety issues of nuclear power plants.
  8. Local communities can contribute to maintenance of fragile ecosystems.
  9. Global concern about climate change rose dramatically after Al Gore made his documentary.
  10. The importance of sustainable development for future generations.
  11. What is at stake with greenhouse carbon gas emissions?
  12. Water is the upcoming hot issue in the Middle East.
  13. Availability and purity of water.
  14. The Burj Khalifa skyscraper in Dubai – the smart innovative energy reuser.
  15. South-American tropical forests.
  16. Global climate change is not only caused by humans.


  1. We need a healthy environment.
  2. The effects of global warming.
  3. Why conserving energy is important.

  7. The effects of industrial and household waste.
  8. What is global warming?
  9. The benefits of organic farming.
  10. Why drought is a serious problem.
  11. The pollution of today’s world.
  12. The importance of reducing, reusing, and recycling.
  13. The effects of environmental degradation.
