Those dedicated to going plastic-free wonder how to dispose of cat litter or buy cleaning products sans packaging. Share your problems – and solutions

• Going plastic-free is as easy as calico bags and reusable coffee cups
  

Plastic has become an environmental disaster. Microplastic pollution has been found in our waterways, fish stocks, salt, tap water and even the air we breathe. Reducing our reliance on plastic by refusing it wherever possible has never been more important, especially as Australia’s recycling system is in crisis.

Yet there are conundrums that continue to defeat even those dedicated to going plastic-free. From bin liners to takeaway containers, Guardian Australia has tried to solve them. And we want to hear from you: share your plastic conundrums and the solutions. We’ll round up the best ideas for a follow-up article.

Larger-than-expected population in Africa gives hope for species survival, scientists say, but animal remains critically endangered

There are far more gorillas left in the world than previously thought, according to a landmark new survey, with numbers as much as double earlier estimates.

However, their populations are continuing to fall fast, down 20% in just eight years, leaving them critically endangered. Furthermore, 80% of the remaining gorilla troops do not live in protected areas, leaving them vulnerable to the threats the researchers summarise as “guns, germs and [felled] trees”.

Low-lying atolls around the world will be overtaken by sea-level rises within a few decades, according to a new study

Hundreds of thousands of people will be forced from their homes on low-lying islands in the next few decades by sea-level rises and the contamination of fresh drinking water sources, scientists have warned.

A study by researchers at the US Geological Survey (USGS), the Deltares Institute in the Netherlands and Hawaii University has found that many small islands in the Pacific and Indian Oceans will be uninhabitable for humans by the middle of this century. That is much earlier than previously thought.

EU carbon prices are not rising to more elevated levels fast enough, France said on Wednesday after meeting with a small group of member states, reiterating its call for a bloc-wide carbon price floor starting with Europe's power sector.

Monthly revenues from EU carbon allowance auctions have for the first time topped the €1 billion mark, providing a major funding injection for governments as EUA prices hold near seven-year highs.

Over 600 NAS members called out ‘the Trump Administration’s denigration of scientific expertise’

Anyone who has read this column over the past five years knows that I tend to be unfettered in my criticism of people who lie and distort climate science to further their political ideologies. At the same time, I believe that the majority of climate sceptics are not willfully wishing to damage this precious Earth that we call home. I believe that there are common areas we can all agree on to take meaningful action to protect the Earth’s environment and build a new energy future; even for people who do not understand climate change or climate science.

But with the election of Donald Trump and his ushering in people who are openly hostile to the planet and future generations, my position has been strained (to say the least). We have had more than a year to observe President Trump’s efforts to roll back Obama-era regulations on pollution from coal plants, weaken pollution standards for motor vehicles, become the only country in the world to reject the Paris climate accord, and gut our climate science budget so that we become blind to what is actually happening.
