There's an orange glow on the night horizon in central Paraguay - no, not a romantic tropical sunset, but a wildfire. Satellites recently registered 1800 of them on a single day.
I was there with ornithologist and bird artist Derek Onley to help with a fledgling conservation project, Para La Tierra, that is trying to protect some of what's left of Paraguay's forests. It's a race against time. Many of the 700 bird and animal species are losing their habitat even while being recorded for the first time.
We stayed near the central town of Santa Rosa del Aguaray, where David Attenborough travelled 50 years before in search of giant armadillos for the London Zoo. He went by boat because the forest was thick and impenetrable, teeming with butterflies, birds and animals in one of the richest biospheres on the planet. Now much of the land is smoke and stubble. American kestrels perch on fence posts, Black and Turkey vultures circle above.
In Paraguay's south and east, around the three main cities of Asuncion, Encarnacion and Ciudad del Este, Atlantic forest was cleared many years ago, mainly for cattle farming. It has since been transformed into treeless grain fields dotted with silos. Paraguay is the world's fourth-largest exporter of soybeans. In 2013, soy exports gave it one of the highest rates of economic growth in the world.
Yet 40 per cent of Paraguayans live in poverty.
