Fewer people, fewer flights C to conserve our planet

Population expert Sarah Harper, from the University of Oxford, says falling total fertility rates are to remain embraced, knowning that countries ought not worry if their human population is not growing (Expert dismisses fears over global fall in fertility, 26 December). Artificial intelligence, migration and a healthier later years mean countries don’t needed booming populations to hold their own individual, she shows. We wish to emphasise the serious benefit, briefly stated in the article, that having one fewer child reduces a parent’s carbon footprint by 58 tonnes of CO2 12 months. In reality, the main contribution of your reduced birth is its long-term contribution towards mitigating our planets atmosphere by reducing CO2 emissions. One major challenge to reducing worldwide CO2 emissions is a large variation between nations: 45 tonnes per capita annually in Qatar, compared with 16.5 the united states, 7.5 in China, 6.5 in great britan, 6.4 within the EU, 1.8 in Indonesia, and 0.3 in least developed countries, in accordance with UN classification.

Reducing global carbon emissions although the developing world industrialises requires both convergence toward rates achieved inside the best industrialised countries and a global lowering of these rates, something the IPCC called “converge and contract”. However, this strategy, with realistic stages of contraction, generally seems to fall far in short supply of it just takes, especially with the present recognition that the previous goal reducing climate change to 2C is insufficient to avoid major adverse impacts. Its here that population decline from falling birthrates can engage in a key element synergistic role while using “converge and contract” strategy, perhaps to begin making the necessity of geoengineering for sustainability only temporary.

I am a grandmother, along with the final thing We would do is book any flight in my grandchildren (How Gatwick drone saga broke my family’s hearts, Letters, 22 December). I will like to leave my grandchildren the planet I spent my youth in, but given current circumstances that can’t happen. I applaud individuals who flew drones over Gatwick, perhaps checking with a tiny amount the advance of worldwide warming. When we don’t act differently soon, the chaos at Gatwick this Christmas will probably be as nothing compared to the catastrophe we seem to be refusing to square.

Re William Westermeyer’s article (In 1993 my agency warned of climate change. In 1995 it turned out abolished, 27 December), of all the manufactured and empty complexities of human life, you can forget that we are all just clinging, white-knuckled and terrified, to this fast-spinning Earth together. In fact ,, no one among us has any additional idea than anybody else of methods much better to cling, or why to even bother continuing. Our only choice comes down to whether we boot our fellow travellers to the void, or make them obtain a firmer grip
