How to prevent environmental damage from harmful chemicals

Not all chemicals are harmful. Water and oxygen are chemicals. Sodium chloride is just table salt, and scary-sounding ethanoic acid is just vinegar. Meanwhile, not everything that’s natural is good for us – cyanide, and snake venom, for example.

But some chemicals can harm the environment or ourselves, either causing immediate damage or building up over time. Those are the chemicals we’re talking about here.

So here’s our Big Green Ideas List for avoiding damage from harmful chemicals.

Lobby your MP to ban bee-killing pesticides

Bees and other insects are essential to pollinate many of the food crops we rely on – but bee populations are in decline due to the use of pesticides, habitat loss and disease.

  • Write to your political representative to encourage them to take a stand against agrochemical and agricultural biotechnology giants like Bayer and Monsanto
  • Follow Greenpeace and Friends of the Earth and support their campaigns against the use of neonicotinoids and similar pesticides

Use environmentally-friendly products

Look for sustainable versions of products

Whatever you’re buying, research whether a more sustainable version exists. Things to consider include:

  • How far it is shipped
  • How much water, chemicals, energy or dye is used in its production
  • Whether the materials can be separated and recycled at the end of the product’s life
  • Does the product gives off Volatile Organic Compounds, and for how long
  • Whether the material is compostable or easily recyclable

Clean with natural, non-harmful products

Good reasons to use natural cleaning products instead of man-made cleaning chemicals include:

  • Keeping hazardous chemicals out of waterways and landfill
  • Avoiding contact with hazardous chemicals in the home
  • Avoiding plastic waste
  • Saving money

Natural, non-harmful products like bicarbonate of soda, white vinegar, and lemon juice are effective, cheap and widely used.

Decorate less frequently – and choose your paint carefully

Paint is made up of a cocktail of chemicals – each chemical has a purpose, but can cause varying amounts of environmental damage or health issues.

Do it by hand

Unblock your shower or sink drain by hand

If you have long-haired people in your household, you’ll probably find that the shower drain blocks regularly. Instead of using harsh chemicals (which harm aquatic life), unblock your shower drain by hand using your fingers, a plunger or a drain snake.

You can make a drain snake out of the plastic straps that keep boxes of paper closed, or building materials together on pallets. Cut the strap to length and snip the edges at intervals to make it jagged, then insert it into the plug hole. Move it around until it catches something, and pull it out. It’s gross but effective.

Weed by hand

Chemicals from weedkillers build up in the soil, reduce biodiversity, and can run off into rivers. Alternatives include using woodchip mulches to suppress weeds in flowerbeds, weeding by hand, regular hoeing, and laying cardboard or old carpet over vegetable beds in the weeks leading up to planting. This reduces weed growth, making hand-weeding easier. Weeds are usually easiest to pull up just after it’s rained.

Hand-weeding can be relaxing and meditative, and it can also be quite enjoyable when done with friends and a cold drink on a summer day (depending on your friends of course).

Choose natural solutions

Choose organic food & clothing

Organic crops are farmed with only minimal use of naturally-derived pesticides and no artificial fertilisers[1].

Organic farming relies on natural predators to maintain ecological balance, and nitrogen-fixing plants and crop rotation to maintain healthy soil. This encourages native wildlife, increases biodiversity, stores large amounts of carbon and protects the soil from erosion. It also prevents harmful chemicals from building up in the soil, rivers and our bodies.

Use companion planting to keep pests away without chemicals

Companion planting means planting certain plants together to deter pests, enrich the soil, and provide shelter. For example:

  • grow French marigolds with tomatoes to repel greenflies and blackflies
  • plant leeks and carrots together as they repel each other’s pests
