We live on an planet which we cannot leave. Sure, astronauts have left the gravitational pull of the plant Earth, but for the general public, we will never get to leave this planet. Even if we could, we would be unable to go to another planet which would be able to sustain life - at least not in this lifetime. Interstellar travel is a very slow business and would take hundreds of years before we reach the next star, and maybe even longer before we reach the next habitable planet. Therefore we should take care of this Earth which we already have.
We can start by reducing our consumption of unnecessary items. This not only means that we buy less, but it also means that we should also prevent wastage. For example, food taken at a buffet should not be thrown away, unless of course, it is unedible. On top of that, simple things such as turning off electrical appliances when not in use, instead of leaving them on standby should also be practised. Contrary to common belief, an electrical appliance still uses energy even when it is not turned on. Another way to reduce our consumption of electricity would thus be to unplug items which are not in use.
Another way to reduce consumption would be to repair old items. Rather than junking them as soon as they wear out, when replacing certain pats of these items would enable the item in question to function well again, we should instead endeavor to repair these items. These items can be anything from shoes, bags, vehicles, and you guessed it, electrical appliances. Reducing consumption can also be done by not buying new items when the current ones still work fine, and by buying more energy efficient items.
Reusing is another way we can cut down on the amount of waste we produce. An industry's output is dependent on consumer demand. The more we buy, the more they make. This causes consumption of energy. Thus, by reusing, we will cut down our demand, and they in turn will reduce their output, reducing the consumption of resources and energy. Plastic bags can be used to pack rubbish, water bottles, refilled and reused, and clothes which have seen better days can be used as rags. On top of all this, the usage of reusable products such as tiffin carriers, tupperware, thermos flasks and melamine boxes (yes, melamine. It doesn't leach into food or drink) should be increased.
Last but not least, is recycling. It used to be my favourite, but recycling is less energy saving than the others. It reduces the amount of energy used to make new items, but if there is no need to get any new items, than there would be a greater reduction in consumption of energy. Either way, recycling is better than just throwing our rubbish into the landfill. While sending our recyclables to a centre might be troublesome to most of us, most of our sanitary engineers (read : pengutip sampah) are more than willing to go through our rubbish to get some extra income. Separating our rubbish will enable them to get all the recycleables possible, and reduce the amount of rubbish we send to the landfills.
We need to rethink the way we do things in life. Practising sustainable development and keeping our carbon footprint small needs to take priority in our lives. Otherwise, living in a landfilll may be the next big thing in housing development in the future.
