Sustainable city—also referred to as a “green city” or an “eco-city”—is an urban enclave whose design, construction, and operation prioritizes the preservation of the natural world alongside the economic, social, and physical health and wellness of the city’s inhabitants.

A landfill site is a location that has been prepared for the purpose of dumping waste, rubbish or debris. Before the land is used to store waste, diggers are used to give it a suitable shape and it is covered with an artificial water-resistant coating to prevent the rubbish from contaminating the soil. The law states that landfill sites must be located away from inhabited areas, as well as areas used for farming or drinking water.

Waste is crushed and compacted—so it occupies as little space as possible—then transported in lorries to outdoor landfill sites, where it is dumped and buried under layers of soil to decompose.

But the truth is that much of this waste take years to decompose due to the conditions of the landfill sites—where there is little oxygen and moisture—and the characteristics of the materials.

Most people in Britain are worried about the impacts of climate change on wildlife in the UK. In one sense that’s not surprising as we're animal lovers.

But an opinion survey found more people concerned about wildlife being affected by climate change than they were about risks to their home from climate-related flooding, or from heat waves and volatile food prices. Of course, an unstable climate will bring all of these ills. But we're certainly stuffed if nature becomes so degraded that we are unable to draw on it for resilience, protection and stability.

Being green is living one’s life in a sustainable way and ensuring that our activities as individuals or a community reflect our planetary resource limits. We depend on our environment for practically everything: from the air we breathe to the water we drink and the food we eat to let’s face it pretty much everything. Going green means that we acknowledge how precious Earth is and the importance of protecting our planet for our future generations
