A New Study Has Found That Climate Change Is Occurring Thousand Times Faster Than The Ability Of Grasses To Adapt...

Global warming could rapidly threaten grasses including staple foods such as wheat and rice that provide half of all the calories consumed by humans. A new study looking ahead to 2070 found that climate change was occurring thousands of times faster than the ability of grasses to adapt. While the research cannot predict what might happen to world food supplies as a result, the authors warn of “troubling implications”. Grass is food, both for many species of animals and humans.

Starvation Warning

Wheat, rice, maize, rye, barley and sorghum are all edible grasses that yield nutritious grains. In many parts of the world and throughout history, wheat or rice famines have led to widespread starvation.

The new research looked at the ability of 236 grass species to adapt to new climatic niches – the local environments on which they depend for survival. Faced with rapid climate change, species wedded to a particular niche can survive if they move to another region where conditions are more suitable, or evolve to fit in with their altered surroundings.

The study found that the predicted rate of climate change was typically 5,000 times faster than the estimated speed at which grasses could adapt to new niches.

Moving Not An Option

Moving to more favourable geographical locations is not an option for a lot of grass species because of limits to their seed dispersal and obstacles such as mountains or human settlements.

Grasses are an important food source for humans — especially rice, wheat and corn. Researchers have said that evolutionary adaptation seems particularly unlikely for domesticated species and even local declines may be devastating for some human populations.

Here's How You Can Help 

In order to ensure that your consumption does not affect your source of food,  the best you can do is not waste food. Wondering how you can do that? The following suggestions will help you in deciding that:

1- Shop Judiciously

Take the lead in making your parents understand the need to shop smart and wise. Plan your weekly schedule and shop your daily vegetables, staple etc accordingly. Shop only as much as you would want to consume in the given week. 

2- Keep A Track Of What You Throw

You may like a food item more than another. But that doesn't mean you stock your home with it in abundance. Stock it in a quantity that will last you for a small period of time than let it rot, or dry up in the fridge. Track what you consume and how much you throw away. By the end of the week, you'll realise the amount that has gone to waste. 

3- Cook As Much Food As You'd Eat That Day:

Whether it is you or your mum, ensure the food that is being cooked suffices you for the time being. Serve only the amount that you'd eat so that there's lo leftover in the plate. If the food cooked has some leftovers, keep them in the fridge for consumption next day or pack it in a container and feed the needy/homeless people on the roads. 

4- Store Food Properly 

Most often, vegetables and fruits dry out or rot when not stored in a cool place. In case, you see your parents forgetting the newly bought vegerables outside, ensure you have stacked them properly in their respective place- be it fridge or a container. 

5- Do Not Overstock

Keeping your fridge cluttered with food will make you forget what's in and what's not. It is better to stock only as much as you think you can remember to eat. If an item has an expiry date, trust your instinct more than anything else. Do not keep the item in fridge thinking it wouldn't harm your body.
