You must have heard about global warming. You must have been seeing the ways the world powers have threatened and been using nuclear weapons to pursue their self-serving agendas (Russia, Ukraine and NATO easily come to mind). What about a global pandemic huge enough to wipe out the human population? What about a massive asteroid invasion? 

Did you know that scientists have predicted that four billion years from now, the increase in Earth’s surface temperature will cause a runaway greenhouse effect, creating conditions more extreme than present-day Venus and heating Earth’s surface enough to melt it? By that point, all life on Earth will be extinct (Ward & Brownlee 2003 p. 142; Fishbaugh et al. 2007 p. 114). The destruction of the earth may come sooner if we do not take drastic actions to curb the trend.

I do not intend to advocate doomsday with this write-up. We must however be aware of how much we have damaged our planet with our activities and understand that it is our responsibility to save the planet. Not every one of us will make it to Mars if anybody ever will. 

1. Stop using plastic

Did you know that plastic does not decompose? This means that all plastic that has ever been produced and has ended up in the environment is still present in one form or another. 

Did you know that people around the world buy 1 million plastic drinking bottles every minute and use up to 5 trillion single-use plastic bags every year? Only about 9 per cent gets recycled. A staggering 8 million tons (7.25 metric tons) end up in the ocean every year, thereby endangering the animals in the ocean. 

What can you do? Drink from a reusable cup instead of buying bottled water. Use a cloth bag instead of a plastic shopping bag. Doing this will divert tons of plastic from our ocean and landfill. 

2. Plant a tree

In 2018 the United Nations’ Intergovernmental Panel on Climate Change (IPCC) report, the U.N. suggests an additional 2.5 billion acres (1 billion hectares) of forest in the world could limit global warming to 2.7 degrees Fahrenheit (1.5 degrees Celsius) by 2050. That might seem like a lot of work, but if we all take it upon ourselves, we can achieve it. One young tree can absorb CO2 at a rate of 13 pounds (5 kilograms) per tree every year. So go ahead and plant a tree or two today! 

3. Switch to Light Emitting Diode (LED) Bulbs

LED bulbs are energy-efficient as they emit light in a very narrow band wavelength.  Equivalent LED bulbs can last around 25,000 hours compared to the 1,000 hours that incandescent bulbs might have lasted.

So you’re wrong If you’re still using incandescent bulbs in your house, office, or factory. You should change them immediately to LED bulbs. 

4. Walk, Bike or Take Public Transit

Walking and biking help to reduce greenhouse gases. Plus you’ll get some good cardio and burn some calories while you do it. So instead of hailing an uber from Falomo to Nigerian Law School, Victoria Island, Lagos, you can simply walk over. You can also use public transit to cover a long distance instead of putting your car on the road. 

5. Conserve water

Even though we may never run out of water because about 71% of the earth is covered with water. Did you know that less than one per cent of it is fit to be used as drinking water? 

So use a dishwasher instead of handwashing. Turn off your faucets while brushing, you’ll save about five gallons of water this way. Instead of draining your cooking water, as it contains nutrients, wait till it cools and use it to water plants outside your house. Keep your showers shorter than five minutes instead of longer, you’ll be saving thousands of gallons of water.
